The second piece of my 3 part series on emitter lights in Maxwell Render is up on the visitor's blog at Method. It's 8 minutes of video that shows you how to control interior lighting in your 3d environments in a different way than placing normal lights in the scene.
Have you tried Maxwell yet? I think it's pretty fun.
I forgot to post about Quickie #7 which was part 1, so here's the link to that video to get you started on the series.
